Honeywell Home THX9421R5021WW Prestige IAQ HD Thermostat (White Front/White Side) | SupplyHouse.com

Users say:
This thermostat is a great choice for those looking for a reliable and easy-to-use HVAC system. It is easy to set up and use, but the TotalConnect mobile app is archaic and borderline useless. Additionally, the customer service from Honeywell is not great, as they are not willing to help with setup and support.
